Bug Description

Please remove glx-alternatives from the archive and blacklist it. The binaries provided by it depend on the way graphics drivers are installed in Debian and this is done completely differently in Ubuntu.

Original bug description:
This bug affects both glx-alternative-mesa and glx-diversions. Both packages require nvidia-installer-cleanup, however, nvidia-installer-cleanup is not installable.

I have the same issue but I get mine when I try to install glx-alternative-nvidia and trying to install the dependencies fails.

I had GL and everything working last weekend (Feb 24 or so). On monday Feb 25, I did apt-get upgrade on my system, and the display driver was broken. I had been using fglrx based on downloading that directly from AMD, but I also had the same problem with the in-stream fglrx and fglrx-updates versions. I had assumed a kernel update in that update set was part of the problem, and I have tried installing fglrx, fglrx-updates, and the latest version from AMD directly with no success so far.

I don't mind working with the radeon driver at this point, but I am still having troubles.

I have no idea if the problems are related to the GL or not, but I would like to get GL running properly using the radeon driver.

It appears that the nvida-installer-cleanup package is missing, and that is why the glx-diversions wont install. I am hoping to find a debian or ubuntu PPA source to install that package as a short term solution.

This is a simple useful tool that package allows you to do "update-alternatives --config glx".
Without it (glx-alternative-fglrx) in my case, I have to manuallly send glx to the AMD driver using pkg-config to compile opengl stuff.
